TCG
One of Strago's cards can use Grand Delta by Dulling Strago, discarding another Strago card and paying three Water CP. Grand Delta deals damage to all the opponent's Forwards equal to 12,000 divided by the number of opponent's Forwards, rounded down to the nearest interval of 1000.

[view·edit·purge]A Grand Trine is a term in astrology. When two planets are 120° apart from each other, they form a Trine, and form a Grand Trine when those two planets each form another Trine with a third planet. By drawing lines to connect the planets directly, this forms an equilateral triangle. The uppercase Greek letter Delta (Δ) likewise has the form of an equilateral triangle.
